摘要： A land vehicle with a disk brake, in particular a utility vehicle with a disk brake, has an axle with a first and a second flange surface for flanging a brake carrier of the disk brake. A first through-opening opens into the first flange surface and a second through-opening opens into the second flange surface. The first through-opening in a first region has a smaller clearance width than in a second region. The first region is located closer to the first flange surface than the second region.

摘要： A hydraulic vehicle brake with a parking brake device, in particular for motor vehicles, includes a brake housing in which a hydraulic service pressure chamber is delimited by a brake piston, wherein hydraulic pressure fluid can be applied to the hydraulic service pressure chamber for carrying out service brake operations so that the brake piston is actuatable along a longitudinal piston axis in order to achieve a braking effect. The parking brake device acts on the brake piston with an actuating device, which actuates a rolling-element ramp-type gear with an electromechanical actuator.In order to achieve a higher rate of overall efficiency as well as a reduced electric energy consumption, a two-step gear is interposed between the electromechanical actuator (7) and the actuating device (4), wherein the first gear step (11, 21, 31) on the inlet side is connected to an output shaft (8) of the electromechanical actuator (7) and the second gear step (12, 22, 32) on the outlet side is connected to the rolling-element ramp-type gear (1, 2, 3).

摘要： An electromechanical actuator in an aircraft brake system may include a stationary body, an actuator drive unit in an actuator drive unit housing, a ball screw coupled to the actuator drive unit, and a ball nut piston coupled to the ball screw. A supplemental back drive mechanism may be disposed between the ball screw and the stationary body. The supplemental back drive mechanism may comprise a spring and a clutch. The spring may store back drive potential energy when the electromechanical actuator is actuated to drive the ball nut piston forward, and may supply back drive energy to the retract the ball nut piston.
